Polyethyleneimine (PEI) is a three-membered ring. Two corners of the molecule consist of -CH2 linkages, while the third corner contains a secondary amine group, =NH. It is processed into highly branched polymers containing up to 25% primary and 50% secondary amine groups. PEI monomers have a high molecular weight (up to two million grams per mole) and can be stored at room temperature. PEI-containing coatings exhibit enhanced antibacterial activity in aqueous media. These coatings were able to bind to two distinct bacterial growths, and their antibacterial ability was enhanced even further when modified with AgNPs.
Market Dynamics:
Growing demand from detergent and water treatment chemicals is driving growth of the polyethyleneimine market. Additionally, growing demand from adhesives and sealants and rapid growth in the manufacturing sector are other major factors fostering market growth. The rise in construction activities is another major factor augmenting market growth. The Building and Construction Authority of Singapore projected the total construction demand to be between SHD 27 billion and SHD 34 billion per year for 2020 and 2021 and between SHD 28 billion and SHD 35 billion per year for 2022 to 2023.
On the other hand, strict environmental regulation is expected to hinder market growth.
